Linearity

±0.02% of E.T. (E.T.= 6 mm / 0.24")

• *2 This value is obtained when the KEYENCE standard object (diffuse white piece or, for the LK-H008/LK-H008W only, metallic piece with specular surface) is measured in normal measurement mode.

Repeatability

0.02 µm (0.01 µm)

• *3 This value is obtained when the KEYENCE standard object (diffuse white piece or, for the LK-H008/LK-H008W only, metallic piece with specular surface) is measured at the reference distance with the average number of measurements set to 16384. The value in parentheses is a typical example of a measurement with the average number of measurements set to 65536 and the sampling cycle at 200 µs.
